What manual transmissions were behind the magnums and do they fit into my car

Im not running an ecu. The magnum will be a carby. I already have 2 automatic cars running a a518 and a 727 so i would like a manual car next for a change. So the manual transmissions that came out behind the magnums are hard to find and need the factory ecu?
In the usa, do you call the manual transmissions a standard transmission?
